- A class of explosive materials that were originally manufactured in the town of Chedde in Savoy, France in the early twentieth century. Closely related to Sprengel explosives, cheddites consisted of a high proportion of inorganic chlorates mixed with nitroaromatics (e.g. nitrobenzene or dinitrotoluene) plus a little paraffin or castor oil as a moderant for the chlorate. Several different types were made, and they were principally used in quarrying.
